Mass-murderer space rock and hash collisions

November 3, 2015

I was on the #IPFS irc channel and some users were discussing about hash collisions, and I read this really clever quote.

A mass-murderer space rock happens about once every 30 million years on average. This leads to a probability of such an event occurring in the next second to about 10-15. That’s 45 orders of magnitude more probable than the SHA-256 collision. Briefly stated, if you find SHA-256 collisions scary then your priorities are wrong
